CARPET-SWEEPER.

SPECIFICATION for ing part of Letters Patent No. 271,284, dated January 30, 1883.

` Application tiled February 9,1882. (No model.)

To all 107mm yit 'may conce Be it known that I, IRGIL H. SNQOK, of Aurora, in the' county of ane andState of Illinois, have invented certa 1 new and useful Improvements in Oarpetveepers; and I do hereby declare that the fo wingis a full, clear, and exact description of he invention, which will enable others skilled n the art to which it ence being had to the acc panying drawings, and to the letters of refer ce marked thereon, which form a part of thi pecication.

My invention is an'imi ved duplex and reversible machine that is imple in 'construction, capacious, readily a Listed and cleaned, not liable to get out of or ,r, and efficient and uoiseless in operation.

lt consists in arrangin nd combining ina case having a handle an( 1 supporting-wheel at each oi' its four corner and a partition in its top and center two r ating brushes having adjustable bearings a friction-wheels on the ends of. theirjournals single detachable tray, and two dirt-conve ng tracks, as hereinafter fully set forth.

Heretoforc two Vrotary rushes have been combined with and opera d in a case having four supporting drive-wh ls at its corners in such a manner as to gat r and deposit dirt in separate detachable tra at the ends of the case. Two rotary brushe connected by pulleys and belts, have also en combined with and operated in a case aving supporting drive-wheels at one end ly in such a manner as to gather dirt and t, positit in aduplex traylocated between the ti n brushes. A dirtconveying track has also een used iu a case having but one rotating ush to adapt it to be used asa reversible s eeper; but in the use of separate dirt rece tacles or trays at each end ofthe case, it tal s much more time and labor to detach, rem fe, empty, and replace the two trays than o ly one, as contemplated by my invention; d in theinstance where one duplex tray hr been placed between the two brushes co ected by pulleys and belts, the brushes al ys rotate toward. each other, and the dirt i rtially lifted and left on or near the surf'ac ot the nap ot' the carpet by the brush in a *ance is brushed downward and into the na and meshes of the of the second brush. By my manner of construction, arrangement, and combination of the several elements and sub-combination the two rotating brushes are made to rotate independently of each other, but always in the same direction relative to each other to always brush the carpet and dirt in the direction the machine is moved,and at the same time carry the dirt picked up by the separate brushes into one and the saine single detachable tray located between the parallel brushes.

Figure 1 of my accompanying' drawings is a perspective view of my machine with a part of the case broken away. Fig. 2 is a bottom view. Fig. 3 is an end view. Fig. et is a transverse sectional view. Fig. 5 is a perspective of my detachable tray. Fig. 6 is a top view of an adjustable plate and bearing for the journals of the revolving` brushes. Fig. 7 is a perspective view of a plate and stub-axle adapted to be adjustably connected with the case to receivethe supporting drive-wheels. Jointly considered, these figures clearly illustrate the construction, operation, and utility of my complete invention.

A represents a case of quadrangular form. It is open at its bottom, and has a cover or roof that inclines downward, iu opposite directions from its center, over the brushes in the ends of the case. The case is preferably made of wood and sheet metal combined, and may vary in size, as desired. t (shown in Fig. 7) is a flat metal plate, having a stub-axle, b, formed integral therewith or fixed thereto, and two slots, 1 2, adapting it to be adjustably fastened against the outside cornerof the case by means ot' clamping-screws c, to receive a wheel, B. By thus attachiuga wheel at each corner the case is elevated and supported upon traveling wheels that also serve as drivewheels to actuate revolving brushes." a (shown in Figs. 1, 3, and 6) is a iiat metal plate and journal-bearing, having slots 3 4, adapting it to be adjustably connected with thesides of the case to support revolving brushesF in such positionsrelative to the wheels B that frictionpulleys d, fixed to the ends of the shaft-jour nals, will engage the peripheries of the wheels B, and transmit motion from the wheels B to the brushes F in such a manner as to cause the brushes to revolve iu opposite directions carpet again by the rever or counteraction from the wheels, but in the same direction rela- IOO tive to each other, as required to brush the nap ofthe carpet and the dirt in the same direction and carry and deposit it into the tray located between the two brushes during the reverse or back and forth movements of the complete machine.

G is a handle thathas aforked shank, adapting it to be pivoted to the top and center portions of the case A, so that it can be turned over the case at pleasure to advance the machine in any direction by pulling or pushing.

H is my detachable tray, preferably made of sheet metal. It corresponds in length with the inside of the case A and in width with the space between the two revolving brushes F. It has a closed bottom, vertical ends, and inwardly-inclined sides k, over which dirt is delivered from the revolving brushes on its opposite sides. rIhe one end, j', has a perforation,f, adapting it to be suspended upon a pin, m, fixed to one of the sides of the case to project inward, as clearly shown in Figs. l and 4. g is a loop fixed to the opposite end ofthe case to project outward through a slot inthe case, and to be engaged by a hook, h, pivoted to the outside of the case, for the purpose of detachably fastening the tray in the case. f is a notch in the top and center ofthe end fof the tray, adapting it to engage the central partition and dirt-directing guide I, fixed in the top and center of the case, as clearly shown in Figs. l and 4. Vacant spaces Loccur between the lower portions of the inclined sides k ofthe detachable trav H and the revolving brushes, through which dust anddirt lifted from the iioor or carpet are drawn upwardby the motions of the brushes and thecurrents of air that result from the actions of the brushes when the brushes revolve toward the inclined sides of the tray. y v.

i" (shown clearly in Figs. l and 2) arejournal-guards in the form of continuous rows of bristles lixedin the ends of the rotating brushes F in such a manner that they will brush against the sides of the case A and prevent carpet ravelings or threads and obstructions from vcoming in contact with and adhering to the journals of the rollers.` Bunches of bristles at distances apart on the ends of rotating brushes have revolved in contact with the'inside of a case, but threads were not thereby prevented from passing between the bunches to wrap upon the journgls, as contemplated by my continuous circumferential guards.

s s (clearly shown in Fig. 4) are sheet-metal plates fixed in the ends of the case A in such positions relative to the brushes F that their central portions will be concentric with the revolving brushes, and their ends eccentric to the same brushes, to form tracks upon which dirt that is drawn into the open spacesL' at the bottom is elevated and carried over the brushes to fall into the tray H, located between the brushes. In lien of the metal plates s, the inside faces of the wooden end pieces of the case A may be made concave to perform the same function.

From the foregoing detailed description of is obvious- I claim as my invention- 1. In acarpet-sweepingmachine,the arrangement and combination of acase supported upon wheels at its corners, and having adirt-directing concave and track at each end, two rotating brushes having adjustable bearings and friction-wheels at their ends, and a detachable tray adapted to be placed between the two brushes, substantially as shown and described, to operate in the manner set forth, for the purposes specified.

2. The detachable tray H, having inclined sides 7c and fastening devices on its vertical ends, in combination with a case, A, having a partition, I, in its top and center, and revolving brushes on opposite sides of said partition, substantially as shown and described,to operate in the manner set forth, for the purposes specified.

3. The detachable lrayt-H, having a perforation, f', and notch f, in one: of its vvertical ends, and a loop, g, at its opposite end, in combination with a case, A, having a fixed pin, m, a fixed partition, I, an opening to admit the loop g, and a hook, h, to engage the said loop, substantially as and for the purposes specified.

4. The duplex and reversible sweeping-machine composed of the following elements, to-wit: the case A, having wheels B at its corners, and a handle, Gr, the revolving and adjustable brushes F, having fixed friction-pulleys d and elastic guards r on their ends, the iixed dirt-guard and partition I, the concave tracks or case ends s, and the detachable tray H, substantially as shown and described, to operate in the manner set forth.
